EXCAVATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,858, dated July 21, 1885.

Application led May 15, 1885.

To all whom it may concern:

Be it known that we, HENRY J. SCHEREE and CHARLES B. VoLE, citizens ofthe United States and residents of Pulaski, in the county of Pulaski and State of Kentucky, have invented certain new and useful Improvements in Excavating-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it apA pertains to make and use the same, reference being had to the accompanying drawings, which forni a part of this specication, and in which- Figure l -is a view of one side of our improved excavatingmachine. Fig. 2 is a view of the side opposite that shown in Fig. l. Fig. 3 is a front View. Fig. 4 is a rear view. Fig. 5 is a horizontal section on line x m in Figs. l and 2, looking downward; and Figs. 6 and 7 are detail views, respectively, of the excavating-buckets and the yoke for the crane-shaft.

Similar letters of reference indicate corresponding parts in all the gures.

Our invention relates to excavating machines, and our object is to provide a machine which shall be powerful, durable, and effective, and at the same time less complicated than most machines are that perform the same amount of work; and to this end our invention consists in the improved construction and combination of parts of sucha machine, which will be hereinafter more fully described and claimed.

In the drawings, A denotes the frame of the machine, which has the uprights B and the cross-beams C and D. Between the sides of the frame A are secured heavy cross-timbers E and the trucks F, upon which the machine is mounted. Upright bearingframes G, H, I, and J are secured to the frame of the machine, and between these bearing-frames are journaled the shafts K, L, and M.

K denotes the shaft to which the power is applied, and which has at its outer end the pulley-wheel N for the purpose, and at the middle of thevr shaft is secured a double-beveled gear-wheel, O7 into which mesh the pinions P and Q, with their clutch-collars attached, for the purpose of engaging them when the levers B and S of the said clutch-collars are shifted. At the other end of the shafts L vthe rollers H' and I'.

(No model.)

and M are respectively a pinion, T, and a worm, U.

Near one end of the frame is secured a heavy plate, V, which forms a bearing for the lower end of the shaft NV of the crane. At the lower end of this shaft is journaleda large circular disk, X, which has about two-thirds of its circumference cogged, and which has its lower face resting upon the plate V, and is held down rmly by a collar, Y, which is secured upon shaft W byv a set-screw. Under the plate V a pin, Y', is 'inserted in a transverse hole in the lower end'of the shaft W. Thus the shaft is rigidly braced inthe plate V.

Journaled upon shaft WV, above 4the'collar Y, is a large'doublebeveled gear-wheel, Z, the lower cogs of which mesh with pinion T at the end of shaft L, andthe upper cogs of which mesh with a large beveled gear, A', which has a sleeve on its outer side with sprocket-teeth, and which is journaled upon an axle or shaft, B', which projects horizontally from the large sleeve C' which encircles thevertical shaft W, and shaft B bears with its outer end in a part of tbe frame of the cra'ne.

D' denotes the lower frame-si1ls of the crane; E', the oblique timbers, and F' the vertical timbers. The sills D' are secured at their inner ends to the cogged diskX, and are made larger in their transverse vertical section at their outer ends, and are provided with bearings for the axles of the sprocket-roller G' and At or near the middle of the sills D are secured. guide-plates J', on their inner sides, to keep the shovels or buckets from striking the sills in their course. A

sprocket-chain, J2, traverses and connects the.

sprocketed sleeve of the gear-wheel A' and the sprocket-wheel K', which is secured upon the same axle as roller G'.

Between the timbers E', at equal intervals, are journaled the rollers I2,which are made in the shape of a spool, the annular enlargements at the ends forming wheels for the buckets or shovels to run upon, and the smaller parts of the rollers form ways for the chain M to run in.

The buckets or shovels are of the construction shown in Fig. 6, and are fastened to the carrying-chain M', about one-third of the'distance from theirtops, and have smaller chains N', connecting their lower ends to the carrying-chain M', so that when the bucket. goes IOO over the uppermost roller of the crane and Ais about to tilt its load, the small chains N' will brace and hold the bucket from sagging from its position in relation to the main chain.

The worm or screw U at the end of shaft M engages the cogged disk X, and turns it when the shaftM is revolved, thus turning the crane.

P' denotes the chute, which may be made in sections, and when notin use may be folded. The frame and crane are braced at different places by stout nutted rods Q'. The crossbeam D is bifurcated at the end adjoining shaft W, and between t-he forks thus made the said shaft is braced vertically and held in position by a hinged bolt, R', which passes through these forks and is nutted at its outer ends. This bolt-and-fork combination givesa spring to the vertical shaft W.

When it is desired to set the machine in operation, the power is transmitted from a stationary engine, which may be placed upon the platform, to the pulley N, which sets the shaft K in motion, and the lever R is shifted, thus engaging the pinion P, and its shaft Lrevolving the pinion T will engage with and turn the large gear Z, and this gear revolves the gear A', with its sprocketed sleeve, and this sleeve operates the chain J 2, which in turn operates the vsprocket-wheel K',with the toothed roller G', and the main or shovel chain M', and the shovels catching their loads as they descend carry them over the crane, and dump them into'the chute as the bucket goes over the uppermost roller.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United Statesl. The frame A, the trucks secured between the sides of the said frame, the upright bearing-frames for the several shafts, pulley-shaft 4o K, pulley-wheel N, double-beveled gear-wheel O, shafts L and M, provided with their loose pinions P and Q, and clutch-collars, levers R and S, for shifting said collars, worm U, and pinion T, in combination with the gear mechanism for working the buckets and turning the crane, substantially as and for the purpose shown and set forth.

2. The frame A, uprights l?, cross-beam D, with its end bifurcated, hinged bolt R', plate 5o V, shaft W, cogged disk X, collar Y, and pin Y', in combination with worm U, the powertransmitting shafts and cogs, and the pinionshifting mechanism, substantially as and for the purpose shown and set forth.

3. The combination ofthe frame A, having uprights and cross beams, as described, plate V, shaft WV, cogged disk X, collar Y, doublebeveled gear-wheel Z, sleeve C', and shaft B', projecting horizontally from said sleeve, gear 6o A', with its sprocketed sleeve journaled upon said shaft, the crane consisting of the sills D', oblique timbers E', and vertical timbers F', connected to the top of shaft W, sprocketchain J2, sprocket-wheel K', toothed roller G', 65 rollers I2, carrying chain M', the buckets secured to the said chain, and the shaft-and-cog power transmitting mechanism, substantially as and for the purpose shown and set forth.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
